Description

[Detailed explanation of the invention] (a) Industrial application field This technology belongs to the field of technology that thaws frozen water pipes in cold regions.

(b) Conventional technology In cold regions such as Hokkaido, water supply pipes installed outdoors are buried below the freezing depth to prevent freezing in winter. Freezing depth is the depth at which freezing does not occur even when the temperature is the lowest. However, water supply pipes may freeze if the backfill is not sufficient when burying them, if the ground has been scraped by other construction work and the burial depth becomes shallow, or if an unexpected cold wave occurs, etc. do.

To thaw frozen water supply pipes, first excavate the water stop valve or water stop point of the frozen pipe, remove the joint of the frozen pipe, and then insert a rubber hose through which steam is passed into the pipe to thaw the ice. It is being said. In this case, steam is generated by heating a simple boiler with a gas burner, but this method has the drawback of being time consuming.
Rubber hoses are used for the work, but if the rubber hoses break or become blocked, the pressure inside the boiler increases, which can be dangerous. Furthermore, since rubber hoses reach high temperatures, they must be handled with care, and the high temperatures also have the disadvantage of causing changes in the material. Known techniques not only have these drawbacks, but also
In essence, the rate of ice melting was slow and the length of ice that could be melted was short. The object of the present invention is to provide a water pipe freezing/thawing device that eliminates the above-mentioned drawbacks.

(c) Means for solving the problem In order to achieve the above purpose, the present invention has the following configuration. A more detailed explanation will be given below with reference to an embodiment shown in the accompanying drawings.

1 is a hot water storage tank, and it is desirable to have a capacity of about 4, but by increasing the capacity, it is possible to work continuously without refilling hot water. 2 is a small battery, and 3 is an electric pump that operates using the small battery as a power source. 4 is a hose that connects to the hot water storage tank, and it is best to use something that is strong and heat resistant, such as a plastic hose. 5 is a nozzle attached to the end of the hose. Reference numeral 6 denotes a casing in which a heat insulating material is housed, and these are housed in a compact manner.

(d) Function When performing ice-thaw work, start the excavation work, and wait until the excavation work is completed before transporting the product of the present invention to the site by car. It is desirable that the water be around 60℃. This is because the hose becomes soft if the temperature is too high. When thawing the ice, the pump is activated and the nozzle is inserted into the frozen water supply pipe, and the pressurized hot water melts the frozen part, so the nozzle is further inserted and this process is continued to complete the thawing operation.

(e) Effects Because the present invention has the above configuration, it is lightweight and easy to move, the water temperature is low so there is no deterioration or softening of the hose, and the pressurized hot water can easily melt ice. It has the effect of eliminating the drawbacks of known products.

Moreover, it is effective not only for outdoor work but also for defrosting water pipes inside buildings.
